Except his input is encoded as Latin-1, not UTF-8. Conversion is still 
trivial though:
---
auto latin1 = cast(ubyte[]) std.file.read("some_latin-1_file.txt");
dchar[] utf = new dchar[](latin1.length);
for(size_t i = 0; i < latin1.length; i++) {
     utf[i] = latin1[i];
}
---
and the other way around.
(The first 256 code points of Unicode are identical to Latin-1)
